...the Double Down, and everybody's peeking-through-covered-eyes reaction to it, is not about logic. It's about balls.The balls of a fast food chain, in the middle of rational America's hand-wringing about obesity and sustainable eating, to come out with a sandwich made of bacon, cheese, mayo-ish sauce and two slabs of fried chicken as the bread. The balls of KFC, which, in the weak-willed '90s, changed its brand from Kentucky Fried Chicken to its lame initials because it didn't want you to have to say the word "fried" every time you spoke its name. The Double-D is so macho, so deeply, dumbly dude, it's a sandwich for people who want to take down Michelle Obama in an arm wrestle.
